Introduction¶
Backporting and the maintenance of a stable release begins when a new stable Ceph release is published. Commits from the master branch are cherry-picked to the stable branch and run through integration and upgrade tests. After a few weeks a point release is published. This repeats until the the stable release is retired. Backporting is focused on fixing bugs and development on the master branch is expected to add new features but both share the same workflow.
